A 0-dimensional quantum code with length \(n\)  has parameters \([[n,0,d]]\) . Such a quantum code represents a single quantum state capable of correcting any \((d-1)/2\)  errors. In practice, 0-dimensional quantum codes can be useful for example in testing whether certain storage locations for qubits are decohering faster than they should [1]}. Moreover, higher-dimensional quantum codes can be constructed by applying Theorem \(\ref {secondary}\)  part 1 to a 0-dimensional quantum code.
